| Abstract: | The purpose of the present study was to evaluate the effect of caffeine ingestion on elite judo players’ mood states, simple reaction time, and muscle power during the Wingate test in the afternoon. Ten elite judo players (age: 21.08 ± 1.16 years, body mass: 83.75 ± 20.2 kg, height: 1.76 ± 0.07 m) took part in this study. The performance variables were measured during two test sessions scheduled at 17:00 h, after placebo or caffeine (5 mg/k) ingestion. The results revealed an increase in anxiety and vigour (p < 0.05) and a reduction in simple reaction time (p < 0.005) following caffeine ingestion. However, muscle power and fatigue during the Wingate test were unaffected. It is concluded that afternoon caffeine ingestion has no ergogenic effect on anaerobic performance. |
